Unformatted text preview: v 1 ( t ) v 1 ( t ) A LPF -B 0 B (b) Sketch the amplitude spectrum of v 2 ( t ): | V 2 ( f )|; label important frequencies and amplitude values. (c) If the output signal of the demodulator is exactly the same as the input signal, i.e., v out (t)= m (t), find out the magnitude, the minimal bandwidth and the maximum bandwidth of the lower pass filter (LPF) shown in Fig. 1-1, i.e., the values of A , the minimum B and the maximum B ....
